Interpretive Summary:

Technical Abstract: Emission of CH4 and other greenhouse gases (CO2, & N2O) is extremely variable in both space and time. It is well known fact that Savannah River receives effluents from variety of anthropogenic activities. These activities could have significant impact on the amount of available C and other chemical & microbial properties of sediments which in turn could play significant role in determining the amount of emission of methane and other greenhouse gases. Therefore, evaluation of emission potentials and capacities of sediments along Lower Savannah River is essential. Total of nine sediment samples collected along lower Savannah River (Savannah, GA) and 20 grams of sediment samples were amended at the rate of either 200 mg C as glucose, 200 mg N as KNO3 or the combination of both per gram of sediment and incubated at 100% moisture level under anaerobic conditions in static chamber (Qopak bottles) for 60 days. Another companion set of untreated sediment samples were incubated for the same period to monitor the emission of greenhouse gases. In this presentation, attention would be focused to evaluate the spatial variation of emission potential and capacities of various greenhouse gases from sediments collected from selected locations along Savannah River near Savannah, GA and to relate the gaseous emissions with selected chemical and microbial properties of the sediments.
